Referring to the drawings, and initially to FIGS. 1 and 2, an electricallock device 1 in accordance with the present invention comprises anelectromagnetic device 10 provided for being mounted or attached orsecured to a supporting structure or member or device 8, such as a doorpanel, a door frame 8, a cabinet, a wall member or the like, for actingor actuating or operating with an electromagnetic plate or armatureplate 80 which is provided for being mounted or attached or secured toanother supporting structure or member or device 88, such as a doorframe, a cabinet, a wall member, a door panel 88, or the like, andarranged for allowing the electromagnetic device 10 and the armatureplate 80 to be acted or actuated or operated with each other in order toselectively lock the door panel 88 to the door frame 8, or toselectively release the door panel 88 from the door frame 8.

The electromagnetic device 10 includes a mounting plate 11 having one ormore apertures 12 formed therein for receiving latches or fasteners (notshown) which may be used to attach or secure the mounting plate 11 toeither of the supporting device 8, 88, and having one or more openings13 formed therein for receiving one or more electrical wires or cables14 which may be required to be engaged through the supporting device 8,88, and having one or more screw holes 15 formed therein for receivingor engaging with a fastening means or device or one or more fasteners 20which may be used to solidly secure a housing 30 to the mounting plate11, in which the housing 30 is provided for receiving the typicalelectromagnetic members (not shown), such as the coils, the plungers,the solenoids or the like. One example of the typical electromagneticmembers has been shown and disclosed in the applicant's prior U.S. Pat.No. 6,299,225 to Chang which may be taken as a reference for the presentinvention.

The mounting plate 11 includes two side channels 16 formed therein andeach formed or defined by a flange 17, in which the flange 17 includesone or more notches 18 formed therein for forming or defining one ormore ears 19. The housing 30 includes one or more passages 31 formedtherein and aligned with the screw holes 15 of the mounting plate 11 forreceiving the fasteners 20, and includes one or more orifices 32 formedtherein and aligned with the openings 13 of the mounting plate 11 forreceiving the electrical wires or cables 14. The housing 30 furtherincludes two side rail ways or grooves 33 formed therein and each formedor defined by a rib 34 for slidably receiving the flanges 17 of themounting plate 11 respectively, in which the rib 34 of the housing 30includes one or more notches 35 formed therein for forming or definingone or more keys or pegs 36.

In operation or in assembling the mounting plate 11 and the housing 30,as shown in FIGS. 3-5 and 2, the electrical wires or cables 14 may firstbe engaged through the orifices 32 of the housing 30 and the openings 13of the mounting plate 11 before or when the mounting plate 11 and thehousing 30 are assembled together. The ears 19 of the mounting plate 11may then be engaged through the notches 35 of the housing 30 and thenengaged into the grooves 33 of the housing 30 respectively in order toengage with the pegs 36 of the housing 30 when the mounting plate 11 ismoved longitudinally relative to the housing 30 to allow the mountingplate 11 to be solidly and stably anchored and positioned to the housing30. The fasteners 20 may then be engaged through the passages 31 of thehousing 30 and engaged with the screw holes 15 of the mounting plate 11for solidly and stably securing and assembling the mounting plate 11 andthe housing 30 together.

Similarly or alternatively or relatively, the pegs 36 of the housing 30may be engaged through the notches 18 of the mounting plate 11 and thenengaged into the side channels 16 of the mounting plate 11 respectivelyin order to engage with the ears 19 of the mounting plate 11 when themounting plate 11 is moved longitudinally relative to the housing 30 toallow the mounting plate 11 to be solidly and stably anchored andpositioned to the housing 30. Similarly, the fasteners 20 may then beengaged through the passages 31 of the housing 30 and engaged with thescrew holes 15 of the mounting plate 11 in order to solidly and stablysecure and assemble the mounting plate 11 and the housing 30 togetherand to solidly and stably retain the ears 19 of the mounting plate 11 inengagement with the pegs 36 of the housing 30 and to prevent the ears 19of the mounting plate 11 from being disengaged from the pegs 36 of thehousing 30.

It is to be noted that the mounting plate 11 may first be solidlyattached or secured to either of the supporting device 8, 88 with thelatches or fasteners (not shown), and the engagement of the pegs 36 ofthe housing 30 through the notches 18 of the mounting plate 11 and withthe ears 19 of the mounting plate 11, and the engagement of the ears 19of the mounting plate 11 through the notches 35 of the housing 30 andwith the pegs 36 of the housing 30 allow the mounting plate 11 to bemoved longitudinally relative to the housing 30 for a relatively smalldistance or moving stroke, and thus allow the electrical wires or cables14 to be suitably engaged through the orifices 32 of the housing 30 andthe openings 13 of the mounting plate 11 while assembling or couplingthe mounting plate 11 and the housing 30 together. In addition, thefastening of the mounting plate 11 to the housing 30 with the fasteners20 allows the pegs 36 of the housing 30 to be solidly engaged with theears 19 of the mounting plate 11.

Accordingly, the electrical lock device in accordance with the presentinvention includes an improved mounting structure for allowing theelectrical wires or cables to be easily mounted or engaged through theelectrical lock device and also for allowing the electrical lock deviceto be easily and quickly mounted or attached or secured to thesupporting structures or members or devices.
